Seeing clicks but no revenue?

Have you ever checked your reports and noticed that you have clicks reported, but no revenue? We'd like to explain why this may happen, as we frequently receive emails and questions on our Help Forum about this issue. What you're seeing may be due to one of the following:

Allowed Sites setupThe Allowed Sites feature allows you to specify a list of sites where ads from your account may be displayed. If you're using this feature, you'll need to make sure that you've listed all sites where you'd like to display your AdSense ad code To check if this is the case, log into your account and visit the 'Allowed Sites' page under your AdSense Setup tab. If the radio button 'Allow any site to show ads for my account ' is populated, you're not being affected by this issue, and you should continue to #2 below. However, if 'Only allow certain sites to show ads for my account' is populated, review the list of sites in the box below -- are all the sites you own listed in this box? If the answer is 'no', you won't be credited for clicks on the missing sites. Please be sure to add all of the sites where you'd like to display your AdSense ad code.We've noticed some confusion among publishers who have entered the sites of advertisers they'd like to see on their pages into the Allowed Sites list. Please know that this is not the case, as it's not possible to request ads for a particular page - the sites you enter into this box can only be sites where your ads can be placed.

Invalid clicks It's possible that you have some clicks that our monitoring system has considered to be invalid. As we've mentioned before, we monitor all clicks and impressions on Google ads for any activity that may artificially drive up an advertiser's costs or a publisher's earnings. Any clicks that our system considers invalid will still appear on your 'Overview' page, under the Reports tab. However, because our advertisers aren't charged for these clicks and impressions, we won't show the earnings for this activity. If you're concerned about suspicious activity in your account, we recommend reviewing your site's logs and letting us know about the situation. Rest assured that AdSense accounts are properly credited for all clicks and impressions we consider to be valid. We'll post your finalized earnings for a given month on your 'Payment History' page during the first week of the following month. For more information about invalid clicks, please review our Help Center.
